Last week, ThinkProgress noted that CNN’s Lou Dobbs is one of the most high-profile “birthers” in America, continuing to demand that Obama present a “long form” birth certificate to prove his citizenship. Dobbs’ focus on the story has been so bad that CNN President Jon Klein eventually sent an e-mail to staffers of “Lou Dobbs Tonight,” declaring that the “birther” story is “dead,” though he later backed down a bit. Dobbs has responded to his critics by calling them “limp-minded, lily-livered lefties” who don’t like that he had “the temerity to inquire as to where the birth certificate was.”
